2017-06-27switchtec: Add "running" status flag to fw partition info ioctlLogan Gunthorpe
This flag lets userspace know which firmware partitions are currently in use as opposed to just active. "Active" means they will be in use for the next reboot, whereas "running" means they are currently in use. If an old kernel is in use, or the firmware doesn't support these fields, the new flag will not be set in the output.

2017-06-27remoteproc/keystone: Fix circular dependencies for ARM configsSuman Anna
Drop the dependency on RESET_CONTROLLER for the Keystone remoteproc driver to resolve some circular dependencies around different choices for RESET_CONTROLLER on common ARM configs.

2017-06-27mtd: st_spi_fsm: remove SPINOR_OP_RDSR2 and use SPINOR_OP_RDCR insteadCyrille Pitchen
The 35h instruction op code has two aliases/macro definitions: - SPINOR_OP_RDCR from include/linux/mtd/spi-nor.h - SPINOR_OP_RDSR2 from drivers/mtd/devices/serial_flash_cmds.h Actually, some manufacturers name the associated internal register Status Register 2 whereas other manufacturers name it Configuration Register hence the two different macros for the very same instruction op code. Since the spi-nor.h file is the reference file for all SPI NOR instruction op codes, this patch removes the definition of the SPINOR_OP_RDSR2 macro. Also the SPINOR_OP_RDSR2 macro will be associated to another instruction op code in a further patch so we need to avoid a conflict defining this macro twice. Indeed the JESD216 rev B specification, defining the SFDP tables, also refers to the 3Eh and 3Fh instruction op codes to write/read the Status Register 2 on some SPI NOR flash memories, the 35h op code still being used to read the Configuration Register/Status Register 2 on other memories.

2017-06-27Merge branch 'nfp-get_phys_port_name-for-representors-and-SR-IOV-reorder'David S. Miller
Jakub Kicinski says: ==================== nfp: get_phys_port_name for representors and SR-IOV reorder This series starts by making the error message if FW cannot be located easier to understand. Then I move some functions from PCI probe files into library code (nfpcore) where they belong, and remove one function which is never used. Next few patches equip representors with nfp_port structure and make their NDOs fully shared (not defined in apps), thanks to which we can easily determine which netdevs are NFP's by comparing the NDO pointers. 10th patch makes use of the shared NDOs and nfp_ports to deliver netdev-type independent .ndo_get_phys_port_name() implementation. Patches 11 and 12 reorder the nfp_app SR-IOV callbacks with enabling SR-IOV VFs. Unfortunately due to how PCI subsystem works we can't guarantee being able to disable SR-IOV at exit or that it will be disabled when we first probe... We must therefore make sure FW is able to deal with being loaded while SR-IOV is already on. Patch 13 fixes potential deadlock when enabling SR-IOV happens at the same time as port state refresh. Note that this can't happen at this point, since Flower doesn't refresh ports... but lockdep doesn't know about such details and we will have to deal with this sooner or later anyway. Last but not least a new Kconfig is added to make sure those who don't care about flower offloads have a way of not including the code in their kernels. Thanks to nfp_app separation this costs us a single ifdef and excluding flower files from the build. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-06-27nfp: reorder SR-IOV config and nfp_app SR-IOV callbacksJakub Kicinski
We previously assumed that app callback can be guaranteed to be executed before SR-IOV is actually enabled. Given that we can't guarantee that SR-IOV will be disabled during probe or that we will be able to disable it on remove, we should reorder the callbacks. We should also call the app's sriov_enable if SR-IOV was enabled during probe. Application FW must be able to disable VFs internally and not depend on them being removed at PCIe level.

2017-06-27nfp: add nfp_app cleanup callback and make flower use itJakub Kicinski
